Hey Jerry, is there a fireblocking conflict by having a door that leads into an attic in a hallway that also acts as an attic over the existing structure?
SECTION R807
ATTIC ACCESS
R807.1 Attic access. Buildings with combustible ceiling or
roof construction shall have an attic access opening to attic
areas that exceed 30 square feet (2.8 m2) and have a vertical
height of 30 inches (762 mm) or greater. The vertical height
shall be measured from the top of the ceiling framing members
to the underside of the roof framing members.
The rough-framed opening shall not be less than 22 inches
by 30 inches (559 mm by 762 mm) and shall be located in a
hallway or other readily accessible location. When located in a
wall, the opening shall be a minimum of 22 inches wide by 30
inches high. When the access is located in a ceiling, minimum
unobstructed headroom in the attic space shall be 30 inches
(762 mm) at some point above the access measured vertically
from the bottom of ceiling framing members. See the California
Mechanical Code for access requirements where mechanical
equipment is located in attics.

No conflict with the two as fireblocking is for blocking off concealed spaces, such as wall stud spaces, from the attic.

An example of fireblocking for walls is at the floor, at the ceiling, and 10 feet horizontally.

The intent is to block the spread of fire from vertical spaces (such as walls) from horizontal spaces (such as floor and ceiling areas) and vice versa.

Sure thing, vertical.. thanks so much.
